Comparison between spiral bite steel plate silo and bolt assembly Silo:
project Bolt assembly bin Spiral bite steel plate warehouse
one Warehouse form Bolt assembly and manual connection on site Spiral bite, automatic lifting, on-site mechanized operation
two Ф 11*H13. Material comparison of 51 meter silo 100g / m2 cold galvanized steel sheet 275 g / m2 double-sided high-quality hot-dip galvanized steel plate
Cylinder wall plate 4.51m 1.2mm plate 5.0m 2.0mm plate
1.12M 1.5mm plate 5.0m 2.5mm plate
3.37M 2.0mm plate 3.51M 3.0mm plate
2.25m 2.5mm plate
2.25m 3.0mm plate
Silo roof 0.6mm plate 1.2mm thick 275 g / m2 double-sided high-quality hot-dip galvanized steel plate
Frameless The skeleton is No. 5 channel steel, with a total of 32 umbrella shaped layout
Column inside cylinder 2m 2mm plate Column A: 8-row channel steel
5.5m 2mm plate [10 #6m, [8 #7.51m]
2m 2.5mm plate Column B: 24 row channel steel
2m 3.5mm plate [10 #3m, [8 #3m, [6.3 #4m]
2m 4.0mm plate
The above is plate bending The above is the national standard channel steel of Jinan Iron and Steel Co., Ltd
Warehouse door, enclosure and ladder Painting treatment after processing Hot dip galvanizing treatment
Bolt strength grade Grade 8.8 There is no need for bolt connection and mechanical engagement on site to prevent bolt stress fracture
three Material requirements Galvanized plate (100g / m2), easy to rust, three years Strict (double-sided hot-dip galvanized sheet 275g / m2 galvanized sheet sgh340, sgh400, sgh440)
Steel plate thickness Thin (0.4-3mm) Thickness (2.0-4.0mm)
four Utilization coefficient of steel plate 87% 63%
five Installation Machinery Simple, manually pull the hoist on site for a long time, and the single warehouse is 10 days Complex, the unit with the latest imported technology from Europe in 2008 is fully automatic, the construction period is short, and the single warehouse is 6 days
six Sealing performance Poor, the sealing rubber gasket is easy to aging, water seepage and difficult to be found. There are materials hanging on the wall due to moisture, which is easy to produce insects Good, no water leakage, fumigation system can be installed
seven strength Poor, the cylinder bolt strength is not enough, easy to break, and the column is bent with thin plate Strengthen the strength of the vertical five-way channel with the national standard thickness
eight Wind and earthquake resistance Poor, there are warehouse turnover accidents in China every year OK, it can resist earthquakes above magnitude 8 and typhoons above magnitude 12
nine Waterproof and leak proof Poor, there are accumulated errors in punching and installation between bolt holes, which need to be corrected on site. There are cracks in punching, resulting in stress and metal fatigue Good, never leaking, can store sewage, grease and other liquids
ten life The bolt strength is grade 8.8, and it is easy to break. The bolt and rubber pad need to be replaced within 5 years, which is easy to rust The normal service life of the industrial zone is more than 30 years and does not need any maintenance
